JACK (m.) - a pet form of JOHN or JACOB (q.v.), thus Eruantalon
or Eruntalon (for a difference could be used Eruantalo
or Eruntalo), or Encaitar

JACKIE (f.) - a pet form of JACQUELINE (q.v.), thus Encaitarince

JACOB (m.) - Heb. 'supplanter'; in QL we can find kaita- "to place" (it may
be not valid and clashes with a word for 'lie'!), whence we could form *encaita-
"replace" close to the meaning of 'supplant', then maybe Encaitar

JACOBA (f.) - feminine of JACOB (q.v.), thus Encaitare

JACQUELINE (f.) - French feminine diminutive of JAMES
(q.v.), thus could be Encaitarince

JADE (f.) - meaning English 'jade' for which we do not have any suitable word;
someone suggested that it might be from Spanish 'piedra de ljada' "stone for pain",
so it might be Naice (= "pain")

JEREMIAH, JEREMY (m.) - Erulehto, see
NWHAGEN; www.behindthename.com says that the name means 'God/Yahweh has uplifted" (which
may actually be the same thing as 'God/Yahweh loosens' which underlies the translation
of Erulehto) and for that reason we may use another element orta "uplift", hence
Eruorto or Eruorton; it was also suggested the name mean 'Gift from
God', then Eruanno (with anna "gift") would the translation

JESSICA (f.) - maybe Heb. 'he beholds'; *ceniro "he sees",
thus Cenire (through it would mean 'she sees'); one Jessica informed
me that this interpretation of the name is incorrect; the name was coined by Shakespeare
and is intended to mean "wealthy/rich/golden one (or queen)"; alma "wealth",
tári "queen", so Almie or Almatári
